目的 对一款自主设计的 EPS 缓冲垫进行结构优化研究 。 方法 首先使用 HyperWorks 和LS-DYNA 做跌落分析， 然后结合模拟等相关数据用 OptiStruct模块进行拓扑优化， 最后对比优化前后结果。 结果 缓冲垫结构优化后平板电视受到的最大冲击加速值小于 45 g， 满足了缓冲保护要求。 结论 缓冲垫结构得到了优化，拓扑优化为此类问题提供了非常有益的探索和借鉴。

Objective To perform structural optimization for a self-designed EPS cushion. Methods First the drop analysis was conducted using HyperWorks and LS-DYNA, then OptiStruct was used to perform topology optimization, combining with simulation and related data, and finally the results before and after optimization were compared. Results The maximal impact acceleration value of the FPTV impacted was less than 45 g after the cushion structure optimization, meeting the requirement of buffering. Conclusion The cushion structure was optimized, and topology optimization provides very beneficial exploration and reference for such problems.
